How to Remove Sap From Windshield

April 8, 2023

When a tree isn’t trimmed, tree sap often falls from its branches and gets stuck on your windshield. Not only is it sticky and unsightly, but it can also cause damage to your vehicle’s paint if left on for too long.

If the sap is fresh and doesn’t have a baked-in stain, the easiest way to remove it is by washing the car. It’s important to park the vehicle somewhere shady (but not under a tree) before starting the cleaning process.

Once the car is cleaned, use a clean microfiber cloth to wipe away any remaining residue from the tree sap on the windshield. It’s best to use a cloth that has been soaked in isopropyl alcohol or mineral spirits, as these solvents soften and loosen the sap.

You may need to repeat the washing procedure, especially if the sap is very stubborn, to get it completely off. Another option is to apply WD40 to the affected area, then cover it with cling wrap before gently scrubbing off any of the sap residue.

Alternatively, you could try freezing the sap, which can harden it and make it easier to chip away at. This method can be effective when the sap is very thick, but you must be careful not to damage your car’s paint job.

Other options for removing stubborn tree sap spots include using an acetone-based nail polish remover or baking soda. For pine sap, you might need a box cutter blade or a non-abrasive scrub brush to break it up and remove it.
